1 Thaler - Frederick William Victory

Struck to commemorate the Brandenburg-Prussian victory in the Battle of Fehrbellin in June 1675, where Frederick William — the Great Elector — routed a Swedish army that had invaded his territories while he was campaigning elsewhere. The speed of his march north, roughly 150 miles in under two weeks with artillery, became the more celebrated military feat. Sweden had held dominance in northern European land warfare for decades; Fehrbellin ended that reputation.

The 1679 date reflects production well after the battle itself, likely tied to the Peace of Saint-Germain-en-Laye, which frustratingly returned most captured Swedish territories under French diplomatic pressure.
